Sharpness at 85mm

For this test, the Nikon AF-S Nikkor 85mm f/1.8G lens was attached to a Nikon D700 body, which in turn was mounted on a sturdy tripod. Exposure delay mode was activated. Tonal and colour variances across the crops are due to changes in natural light during the session.

Centre sharpness remains high through from f2.8 to f/11, with the minimum aperture of f/16 being slightly affected by diffraction. The edges aren't nearly as sharp as the centre, with f5.6-f/11 producing the sharpest results.
